Struct LogEntry 

pub struct LogEntry {
    pub term: u64,
    pub index: u64,
    pub data: Vec<u8>,
}

A single entry in the Raft log.

Each entry carries the term in which it was created and an opaque command payload. The state machine interprets the payload; Raft only cares about term and index for consistency.

Fields

term: u64

The term when this entry was received by the leader.

index: u64

Log index (1-based, monotonically increasing).

data: Vec<u8>

Opaque command for the state machine. Empty for no-op entries (appended by newly elected leaders per Raft paper §5.4.2).

Trait Implementations

impl Archive for LogEntry

where u64: Archive, Vec<u8>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<LogEntry>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedLogEntry

The archived representation of this type.

type Resolver = LogEntryResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <LogEntry as Archive>::Resolver, out: Place<<LogEntry as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for LogEntry

fn clone(&self) -> LogEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LogEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LogEntry

fn deserialize<__D>( __deserializer: __D, ) -> Result<LogEntry, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<LogEntry, __D> for <LogEntry as Archive>::Archived

where __D: Fallible + ?Sized, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<LogEntry, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for LogEntry

fn read<R>(reader: &mut R) -> Result<LogEntry, Error>

where R: Read<'__msgpack_de>, LogEntry: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for LogEntry

fn eq(&self, other: &LogEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<__S> Serialize<__S> for LogEntry

where __S: Fallible + ?Sized, u64: Serialize<__S>, Vec<u8>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<LogEntry as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for LogEntry

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for LogEntry

fn write<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Write,

Writes the MessagePack representation of this value into the provided writer.

impl Eq for LogEntry
